| Ship name (ship code) | RV Corystes (74RY) |
| Cruise identifier | COR10/00 |
| Cruise period | 2000-07-25 — 2000-08-08 |
| Status | Completed |
| Port of departure | Lowestoft, United Kingdom |
| Port of return | Lowestoft, United Kingdom |
| Purpose | Research |
| Objectives | 1. To undertake a beam trawl survey in the southern North Sea and eastern English Channel as part of an international programme to i) obtain fisheries independent data on the distribution and abundance of commercial flatfish species and ii) derive age compositions of sole and plaice for use in the assessment of stock size.
2. To collect biological data including maturity and weight at age of commercial flatfish and non-commercial fish by-catch. 3. To quantify the seabed sediments and epibenthos using 4m beam trawl by-catch data, a specifically designed 2m beam trawl, and remote acoustic seabed discrimination systems (QTC). 4. To carry out a detailed survey on and around the Hastings Shingle Bank. 5. To collect biological data on the reproductive cycle and population genetics of the ctenostomate bryozoan genus Bowerbankia. |
